The challenge of securing hybrid AD identity
Implementing MFA in an on-prem or hybrid AD environment often requires infrastructure changes or adds management overhead.
Many MFA solutions are designed for cloud-first identity and struggle with core AD realities, making it difficult to apply one MFA solution across Windows logons, RDP, offline scenarios, SaaS access, and privileged actions like UAC elevation.
Keep IAM simple with UserLock
UserLock adds modern MFA and access controls to AD, giving IT full control of AD identity access to network and SaaS resources.
Deploy quickly via lightweight agents, no changes to AD schema
Enforce granular MFA across Windows, RDP, RemoteApp, SaaS, UAC, IIS, and more
Apply contextual access controls (device, time, location)
Limit concurrent sessions and block concurrent logons
Monitor and alert on real-time AD identity access
Maintain audit trails for compliance and IT forensics
How UserLock works
A user attempts to log in to a workstation, server, or remote session
UserLock intervenes during AD authentication via a custom credential provider
MFA and contextual access policies are verified before the session opens
Every access attempt and session activity is logged, monitored, and fully auditable

I can’t trust that someone is a legitimate user or administrator just because they were on a computer on-site. Now I can verify who’s using our computers with UserLock. ”

Simple and reliable.
I've tested several 2FA software. In the end, I stuck with UserLock because it requires no administrative effort. I really like the reports and the control of who is connected to which device. ”
